I wrote a small Javascript runner in the browser where you can play with the formula. You can save your fractal as a URL and share with friends. Of course, I provided a Mandelbrot set as the default fractal.
As always, this is all open-source including the code for this page. See the source on github and feel free to fork and have fun with it.
Happy fracting!
Feel free to submit your own fractals. A few interesting cases:
